Definitions

  • the invention relates to packaging technology, for instance roll-fed carton packaging systems for liquid food. More particularly, it is presented a sealing member comprising a package volume controlling section, an insert to be placed in a socket in the package volume controlling section, a sealing apparatus comprising the sealing member, and a method for customizing a sealing apparatus.
  • the convex portions can be provided at different places of the sealing apparatus, such as the sealing members. More particularly, the convex portions of the sealing members can be placed on sections of the sealing members placed next to sealing surfaces of the sealing members. By having convex portions placed in this way, the convex portions will during the sealing stage provide for that a top panel and a bottom panel, respectively, of the package being formed are pushed inwards, towards a mid-portion of the tube, and thereby a more controlled forming of the package can be achieved.
  • the prior art successfully achieves to present a packaging system that is reducing a problem of having packages produced with an inconsistent volume content.
  • having the convex portions set correctly may be a cumbersome and lengthy process.
  • a sealing member comprising a sealing section configured to interact with a sealing band of a tube of packaging material in a sealing stage, and a package volume controlling section configured to interact with a first area next to the sealing band of said tube of packaging material in the sealing stage, wherein said package volume controlling section is provided with a socket for holding an insert.
  • the socket is provided with socket protrusions for holding the insert in place.
  • the socket protrusions extend in a sliding direction perpendicular to a surface normal of said package volume controlling section and the socket is arranged for receiving the insert via a section placed opposite to the sealing section.
  • the sealing member may further comprise a tube controlling section configured to interact with a second area next to the sealing band, wherein the first area and the second area are placed on each sides of the sealing band in the sealing stage, wherein the tube controlling section is provided with an additional socket for holding an additional insert.
  • the sealing member may further comprise an inductor.
  • an insert comprising a convex portion configured to interact with the first area of a tube of packaging material in a sealing stage, wherein the insert is configured to be held in a socket of a sealing member according to the first aspect.
  • the insert may be provided with insert protrusions configured to interact with socket protrusions of the socket.
  • the insert may be configured to be held in the socket of the package volume controlling section.
  • the insert comprises a first section configured to be placed in the socket, and a second section placed on top of the first section and the second section may be placed offset the first section.
  • a sealing apparatus comprising a first sealing member and a second sealing member, wherein the first sealing member and the second sealing member both comprising a package volume controlling section provided with a socket holding an insert according to the second aspect.
  • the first sealing member is provided with an inductor and an active surface of the sealing section, and the second sealing member may be provided with at least one pressure pad for providing a counter-pressure in a sealing stage.
  • the insert may be placed in the socket by sliding the insert into the socket.
  • a transversal sealing can be made in a lower end of the tube by using a sealing apparatus 110.
  • the sealing apparatus 110 has two main functions - providing the transversal sealing, i.e. welding two opposite sides of the tube together such that the product in a lower part of the tube, placed downward the sealing apparatus, is separated from the product in the tube placed upward the sealing apparatus, and cutting off the lower part of the tube such that the package 108 is formed.
  • the step of cutting off the lower part may be made in a subsequent step by a different piece of equipment, or by the consumer if the packages are intended to be sold in a multi-pack.
  • a general principle of the sealing apparatus 110 is illustrated in further detail.
  • the tube 104 can be fed from above since this provides for that product can be held inside the tube.
  • a sealing stage S a first jaw provided with an induction heat sealing device 200 and a second jaw provided with a counter pressure device 202 are moved towards each other such that two opposite sides of the tube 104 are pressed towards one another.
  • heat can be provided by inducing eddy currents in the packaging material while pressing the two opposite sides together. The heat provides for that a plastic layer of the packaging material is melted, which in turn provides for the plastic layer can be used for making sure that the two opposite sides can attach to each other and stay together after the jaws are removed.
  • a cutting stage C the lower part of the tube 104 can be cut off such that the package 108 is formed.
  • the jaws can be moved together with the tube 104 in a tube feeding direction A during the sealing stage S and the cutting stage C.
  • volume forming flaps 204a, 204b can be used. More specifically, by using these the tube 104 having a round cross-section may be steered into a package 108 having a rectangular cross-section in a controlled manner.
  • the sealing device can be provided with two inductors, a first inductor 206a and a second inductor 206b.
  • the first inductor 206a is arranged above the second inductor 206b.
  • a knife 208 can be used for cutting off the lower part of the tube and thus form the package 108.
  • the knife 208 and the first and second inductors 206a, 206b are provided in the sealing device, but other arrangements are also possible.
  • the knife may be provided on the other side of the tube, in the counter pressure device, or the cutting step may be performed by a separate device downstream the sealing device.
  • the induction heat sealing device 200 or other sealing device used for providing power such that plastic layers in the packaging material melts
  • the counter pressure device 202 or other device for providing a counter pressure
  • sealing members may generally be referred to as sealing members.
  • Fig 3a, 3b and 3c illustrate a sealing member 300 similar to the sealing device 200 illustrated in fig 2 .
  • the sealing member 300 may comprise a main body 302, which may comprise a section 304 placed opposite to the sealing section.
  • an inductor may be provided in the main body.
  • the inductor may, as explained above, be used for inducing eddy currents in the packaging material during the sealing stage S.
  • the inductor may be fed with electrical power via a connector 306.
  • a first insert 308 and a second insert 310 may be used.
  • the sealing member 300 is illustrated with the first insert 308 provided with a convex portion facing downwards and in fig 3b the sealing member is turned upside down with the first insert 308 facing upwards.
  • a section of the sealing member in which the first insert 308 is placed in fig 3a may be referred to as a package volume controlling section, and the opposite side in which the second insert 310 is placed may be referred to as a tube controlling section.
  • the first insert 308 By having the first insert 308 facing downwards, as illustrated in fig 3a , an area of the tube beneath the sealing area will be pressed inwards, which will result in that the volume of a package being formed can be controlled with increased accuracy. Put differently, if the package is produced with a bottom section facing upwards and a top section facing downwards, a bottom panel of the package being formed may be pressed inwards by the convex portion of the first insert 308.
  • the inserts 308, 310 may be provided with or without the convex portion.
  • a reason for this is that the sealing member 300 may be symmetrical such that it can be mounted in the sealing apparatus 110 with the connector 306 facing in two opposite directions. This is advantageous for at least two reasons. First, one and the same member may be used for both mounting alternatives, which provides efficient supply chain. Secondly, by mounting a number of sealing members with every second of them facing in the same direction more room is provided for service technicians.
  • the sealing member 300 can easily be adapted such that irrespective of how it is mounted the convex portion may be facing downwards.
  • inserts with different types of convex portions may be provided.
  • a particular type of packaging material may have properties making a particular design of the convex portion more beneficial than others.
  • the product in the tube may have an effect on how the convex portion is to be designed.
  • a socket 312 provided with socket protrusions 314a, 314b may be used for holding the insert 308, 310 in place.
  • the inserts 308, 310 may be slided into position and after being slided into position and the sealing member is attached to the sealing jaw with the sealing section facing the sealing jaw the inserts are restricted from sliding out of position.
  • the first insert 308 is illustrated in further detail in fig 4 .
  • the first insert 308 can comprise a first section 400 arranged to be slided into the socket 312 of the sealing member and a second section 402 comprising the convex portion.
  • the first section 400 and the second section 402 may be offset in relation to one another.
  • An advantage of this is that the socket 312 can be kept small without compromising on placement of the convex portion. Since the main body 302 of the sealing member 300 may comprise an inductor and other devices related to this, possible negative effects of having an extensive socket may be avoided.
  • the first insert 308 may be provided with insert protrusions 404a, 404b arranged to cooperate with the socket protrusions 314a, 314b.
  • An advantage of sliding the insert in place instead of having it screw mounted is that the latter is requiring holes in the main body 302. These holes affect the electromagnetic profile negatively, and therefore avoiding making holes for fastening the insert is beneficial for the functionality of the sealing apparatus. Further, drilling holes in the main body 302 is negatively affecting the durability of the sealing member.
  • a positive effect of having the insert slided into position from the section 304 facing the sealing jaw is that the insert may easily be removed from the sealing member.
  • the sealing member may be attached to the sealing jaw by screws. Thus, as an effect, only a screw driver is required for replacing the insert.
  • the second insert 310 is illustrated in further detail.
  • the second insert 310 may be provided with insert protrusions 502a, 502b arranged to cooperate with the socket protrusions 314a, 314b.
  • the second insert 310 is not provided with a convex portion, but is serving as a placeholder.
  • step 602 the sealing member can be de-mounted from the sealing apparatus.
  • the insert placed in the socket may be removed in step 604.
  • another insert may be placed in the socket in the package volume controlling section in step 606.
  • an additional insert may be placed in an additional socket placed in the tube controlling section in step 608.
  • the sealing member may be mounted back into the sealing apparatus in step 610.
